EU Falling Apart - Consequences?

[Peh]

Just to add some more fuel:
These are the things that probably could happen(?):

- Every country would make rules like they want.
-> Has pro and cons: Questionable chemicals in food could be sold. Fracking could be made easily accessible in Europe or not(Currently it is not allowed)

- More expenses for Tourists and more difficult to travel between states.

- Trading could be more difficult due certain regulations.

- Easier to deal with immigrants by not letting them into the country. (Putting up fences and walls around the borders?) Controls at the borders make it also difficult for trading goods. Takes more time. Goods will get overall more expensive for everyone?

- Poor countries have it difficult to grow or maybe it's even more impossible.

- Maybe building Nuclear Power Plants when the feel like it? More Coal plants? No one gives a crap about global warming?

- Cooperation between states against criminals or terroristic groups will be more difficult.

- Increase in racism against immigrants??

- Friendship(?) between states can brake apart.

- The worst I have heard is that a new war can spark.
